Abstract: APPARATUS AND METHOD FOR GENERATING SOFT X-RAY LASING ACTION IN A CONFINED PLASMA COLUMN THROUGH THE USE OF                   A PICOSECOND LASER     ABSTRACT           Soft X-ray lasing action may be obtained by focusing a high power, picosecond laser pulse on a confined plasma column. The plasma column is created by focusing a CO2 laser pulse on a target such as carbon.  A strong cylindrical magnetic field contains the plasma and causes it to assume the shape of a column.  While the plasma column is cooling rapidly due to radiation losses, a second high power laser with a duration time of approximately 1 picosecond is focused Along the central part of the plasma column.  The powerful picosecond laser provides  strong selective excitation of the ions for enhancement population inversion and the creation of high gain for X-ray lasing action.  According to alternative embodiments, other multi-Z elements such as molybdenum, aluminum and krypton can be used to create a lasing medium in the plasma column.

Abstract: ABSTRACT It has been found that layers which include arsenic and/or zinc can have an adverse effect upon optoelectronic semiconductor devices such as lasers. This is reduced by treatments in which arsenic and zinc are excluded. Preferably the substrate is cooled from reaction temperature in the presence of a mixture of hydrogen and PH3 (replacing AsH3 and/or Zn(CH3)2 used to grow the final layer). Alternatively, devices having a contact layer of heavily p-type gallium indium arsenide are improved by the deposition of a protective layer of indium phosphide. This layer is removed immediately before metalisation. Even though the protective layer is not present in the final product it has a beneficial effect.

Abstract: Abstract As a flexible container used primarily for making wine in, it is made of laminated plastic film,or films which are hermetically sealed along the seams to produce a triangular air-tight bag. The container features a filling spout and a pressure relief vent at the top. At the bottom is another spout to which a cap, valve or hose can be attached for draining. The container which when full of wine, appears like an inverted cone allowing the 'sediment',(which is a waste byproduct of the fermenting process), to sink and slide down the inside walls of the container and accumulate at the bottom near the drain spout. When the user wishes to remove the sediment, a clamp is then attached to the container just above the sediment level, and the sediment can then be easily removed through the drain spout, with the clamp preventing loss of the wine during this procedure.

Abstract: ABSTRACT An electronic computer orders magazines of multiple titles from dispensing units, each of which has a single title assigned to it, and these orders are or-ganized by carrier route, that is to say all magazines for subscribers of a specific carrier route are ordered in sequence.  The orders are directed to a magazine dispensing unit which has a different pocket for each title, and these pockets deliver to the conveyor one after the other magazines that fill the subscriptions to which the various addresses pertain.  The computer also causes the insert dispensing unit to deposit on the magazines as those magazines pass under the unit inserts that are appropriate to the magazine and its subscriber.  Next a wrapping machine places a transparent polymer film around the magazine and any insert which is on it.  Then the conveyor carries the magazine past an ink jet printing unit where the subscribers name and address are applied to the polymer envelope, the printing unit likewise being connected to the computer.  The conveyor thereafter de-posits the magazines one after another in a stacking machine, which is also under the control of the computer, and it arranged the magazines in stacks which comply with the requirements for carrier route sortation, in that each stack has magazines addressed to a single carrier route, contains the minimum number of magazines, and does not exceed the prescribed weight.

Abstract: ABSTRACT OF THE DISCLOSURE      A pulse oximeter or plethysmographic device utilizes light  varying  in  intensity  at  a  predetermined  carrier frequency.  A passive resonant circuit having a resonant frequency substantially equal to the carrier frequency is connected between the photodetector and the first ampli-fier.  The resonant circuit serves to suppress spurious DC and low frequency components such as those due to ambient light and ambient light flicker and also to suppress high frequency interference.  Because ambient light signals are suppressed,  there is no need for dark current correction or restoration.   Suppression of ambient  light  and other interference upstream of  the front end amplifier avoids saturation of the amplifier and permits use of a front end amplifier having high gain.

Abstract: ABSTRACT         Pultruded marking devices (29,42,45,48,50,55,57,58) made of fiber reinforcement materials (10,14,16,17) embedded in a cured polyester resin matrix (65) that contains about 2% to 25% by weight of cellulose solid particulates.  Unidirectional reinforcement materials (10) are the major portion of the reinforcement materials and form about 30% to 60% by weight of the total weight of the marking devices.  The addition of cellulose particulates to the polyester resin formulation improves the "fill" of the resin and reinforcement package.          The term "fill" means the ability of the total resin and rein-forcement package to utilize all of the available space in the pultrusion die.  A package which does not exhibit good "fill" results in a cured pultruded part that has unacceptable surface imperfections, such as hollow portions similar to dents or gouges, which can range from about 1/2 inch to as much as 6 inches long in the finished article.
